Express the alternative hypothesis in symbolic form. an automobile technician claims that the mean amount of time (in hours) per domestic car repair is more than that of foreign cars. assume that two samples are independent. let the domestic car repair times be the first population and the foreign car repair times be the second population.

: mu1-mu2=0

: mu1-mu2>0

Step-by-step explanation:

Let mu1 be the mean amount of time (in hours) per domestic car repair

and mu2 be the mean amount of time (in hours) per foreign car repair

According to the claim of the automobile technician, the mean amount of time (in hours) per domestic car repair is more than that of foreign cars.

Then null and alternative hypotheses can be stated in symbolic form as

i belive those are the ones that are under 90 degreese.

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
